The writer would determine the outcome... and if it came out to a battle it could go either way. Venom has gone toe to toe with being much stronger than himself including the Juggernaut and Ghost rider without any type of power boosts (who are magic powered fyi).

Venom isn't out form this fight even by a long shot. the alien symbiote can take a heft beat down and isn't given the respect it deserves.

for that my vote goes to Venom, and in no way is this an easy victory, no way...
